The control module may be configured to receive an indication from a user interface to transition the vehicle into an extended park mode, and responsive to the indication, instruct the plurality of vehicle control modules to perform operations to reduce their respective key-off loads on the vehicle. A cloud service may be configured to receive, over a wide-area network responsive to user input to a mobile device, an indication to transition a vehicle associated with the mobile device into an extended park mode, and responsive to the indication, provide a message over the network to the vehicle to instruct the vehicle to perform operations to reduce key-off loads of a plurality of vehicle control modules of the vehicle.

TECHNICAL FIELD

Aspects of the disclosure generally relate to an extended park mode fora vehicle, in which battery key-off load is reduced.

BACKGROUND

Vehicle key-off load may be defined as a current drain on a battery of avehicle when the ignition key is in the off position. In some cases,when a vehicle is parked for an extended period of time, key-off loadmay cause a significant reduction in the state of charge of the vehiclebattery. Some drivers limit key-off load by electrically disconnectingthe battery when leaving the vehicle parked for an extended time.However, for some vehicles the battery may be difficult to access, andin any event such approaches are inconvenient for the driver.

DETAILED DESCRIPTION

As required, detailed embodiments of the present invention are disclosedherein; however, it is to be understood that the disclosed embodimentsare merely exemplary of the invention that may be embodied in variousand alternative forms. The figures are not necessarily to scale; somefeatures may be exaggerated or minimized to show details of particularcomponents. Therefore, specific structural and functional detailsdisclosed herein are not to be interpreted as limiting, but merely as arepresentative basis for teaching one skilled in the art to variouslyemploy the present invention.

A vehicle may implement a setting configured to allow a user totransition a vehicle into an extended park mode in which key-off load isminimized. To allow the vehicle to enter the extended park mode, acontrol module of the vehicle may be configured to issue a command toother modules of the vehicle to cause those modules to transition to areduced power mode. This will accordingly reduce the load on the batteryduring anticipated extended vehicle stand times. In an example, thedriver may command the vehicle to enter the extended park mode through amenu selection on a vehicle graphic user interface (GUI). In anotherexample, the driver may remotely command the vehicle to enter theextended park mode using a phone or other mobile device.

When the vehicle is in the extended park mode, the vehicle modules maybe configured to perform operations to reduce their respective key-offloads on the vehicle. These operations may include, for example, (i) formodules that perform periodic polling of input, to slow down or stoptheir polling, (ii) to disable periodic clock accuracy adjustments toallow the human-readable clock to drift, (iii) to turn off tire pressuremonitoring system (TPMS) monitoring, (iv) to turn off door sensors forpassive entry features (e.g., excluding the driver door), (v) to limitembedded modem functionality and telecommunication updates, such as toallow unlock, remote start and disable extended park mode, (vi) todisable approach detection features, (vii) to disable fuel operatedheater systems, (viii) to disable extended play mode, (ix) to disableilluminated entry/exit lighting, (x) to limit or eliminate battery saverduration control length of interior lighting, (xi) to disable powertrainwake on door ajar, (xii) to disable wake on oil minder, and (xiii) todisable global positioning system (GPS) updates. For hybrid or pureelectric vehicles, these operations may also include, for example, (i)to discontinue cabin preconditioning, (ii) to discontinue battery driveconditioning, and to (iii) disable scheduled-charge-not-occurringsignals.

To allow the vehicle to exit the extended park mode, the control moduleof the vehicle may be configured to issue a command to other modules ofthe vehicle to cause the modules to transition back to the normal powermode. In an example, the vehicle may automatically transition from theextended park mode to the normal mode on the next key start. As anotherpossibility, the vehicle may transition back to the normal mode based onthe key start and selection to turn off extended park mode by way of aprompt to the driver via the vehicle user interface (e.g., cluster,center stack, etc.). As some other possibilities, the driver may commandthe vehicle to exit the extended park mode through a menu selection onthe vehicle GUI or by way of a menu selection from a radio frequencyconnected device or telecommunication device.

FIG. 1 illustrates an example vehicle 100 implementing an extended parkmode. As illustrated, the vehicle 100 includes a battery 102, an engine104, powered systems 106 and one or more vehicle buses 108. The poweredsystems 106 include a body control module 110 and plurality of systemmodules 112. The modules 110, 112 are in communication over the bus 108and configured to perform various vehicle functions under the power ofthe vehicle battery 102.

The battery 102 may include various types of rechargeable batteryconfigured to supply electric energy to various components of thevehicle 100. In an example, the battery 102 may be a 12 Volt lead-acidbattery. The battery 102 may be configured to power the starter motor114 and the ignition system 116 of the engine 104 when the engine 104 isnot running, and may receive electric charge from the alternator 118when the engine 104 is running. In another example, the battery 102 mayinclude a traction battery or battery pack configured to store energythat can be used by one or more electric machines of the vehicle 100that can provide propulsion and deceleration capability, whether theengine 104 is turned on or off.

The body control module 110 may be configured to support variousfunctions of the vehicle 100 related to control of current loads feedingoff the battery 102. Examples of such current loads include, but are notlimited to, exterior lighting, interior lighting, heated seats, heatedwindshield, heated backlight, and heated mirrors. Additionally, the bodycontrol module 110 may be configured to manage vehicle 100 accessfunctions, such as keyless entry, remote start, and point of accessstatus verification (e.g., closure status of the hood, doors and/ortrunk of the vehicle 100).

The vehicle bus 108 may include various method of communicationavailable between the system modules 112, as well as between the bodycontrol module 110 and the system modules 112. As some non-limitingexamples, the vehicle bus 108 may include a controller area network(CAN) bus and/or an Ethernet network.

The body control module 110 may include various types of computingapparatus to facilitate the performance of the functions of the bodycontrol module 110. In an example, the body control module 110 mayinclude a processor 120 configured to execute computer instructions, anda storage medium 122 on which the computer-executable instructions maybe maintained. A computer-readable storage medium 122 (also referred toas a processor-readable medium 122 or storage 122) includes anynon-transitory (e.g., tangible) medium that participates in providingdata (e.g., instructions) that may be read by a computer (e.g., by theprocessor 120). In general, a processor 120 receives instructions, e.g.,from the storage 122, etc., and executes these instructions, therebyperforming one or more processes, including one or more of the processesdescribed herein. Computer-executable instructions may be compiled orinterpreted from computer programs created using a variety ofprogramming languages and/or technologies, including, withoutlimitation, and either alone or in combination, Java, C, C++, C#,Fortran, Pascal, Visual Basic, Java Script, Perl, PL/SQL, etc.

The plurality of system modules 112 may be configured to perform variousvehicle functions under the power of the vehicle battery 102. Asdepicted, the modules 112 are represented as discrete modules 112.However, the modules 112 may share physical hardware, firmware, and/orsoftware, such that the functionality from multiple modules 112 may beintegrated into a single module 112, and that the functionality ofvarious such modules 112 may be distributed across a plurality ofmodules 112.

As some non-limiting module 112 examples, a powertrain control module112-A may be configured to provide control of engine 104 operatingcomponents (e.g., idle control components, fuel delivery components,emissions control components, etc.) and for monitoring status of suchengine operating components (e.g., status of engine fault codes); abattery management module 112-B may be configured to compute and providestate of charge status (e.g., to the powertrain control module 112-A orothers); a radio transceiver module 112-C may be configured to send andreceive messages by way of a wireless network or paired communicationsdevice; a telematics control unit 112-D may be configured to send andreceive commands from the paired communications device or wirelessnetwork connection using the facilities of the radio transceiver module112-C (e.g., to provide low battery alerts to a driver's phone or to aweb database); a climate control management module 112-E may beconfigured to provide control of heating and cooling system components(e.g., compressor clutch, blower fan, temperature sensors, etc.); aglobal positioning system (GPS) module 112-F may be configured toprovide vehicle location information; and a user interface module 112-Gmay be configured to provide vehicle status information to a driver,such as fuel level info, engine operating temperature information, andcurrent location of the vehicle 100.

The system modules 112 may be configured to perform certain vehiclefunctions when the engine 104 is running. In other cases, the systemmodules 112 may be configured to perform at least a subset of theirfunctions even when the vehicle is parked and the vehicle engine 104 isnot running (sometimes referred to herein as keyed-off). As somenon-limiting examples of module 110, 112 functionality that may beperformed when the vehicle is keyed off, the body control module 110 mayperform periodic polling for keyless entry, passive entry, or otheraccess management features, the battery management module 112-B mayperform battery drive conditioning and warn regarding scheduled chargesthat are not occurring, the radio transceiver module 112-C may receivecommands such as unlock or remote start, the climate control managementmodule 112-E may perform cabin preconditioning in anticipation of anexpected trip by the driver at a time prescheduled with the vehicle 100,and the GPS module 112-F may provide location updates for the vehicle100.

Vehicle functions performed by the body control module 110 and systemmodules 112 when the vehicle is keyed off produce a current drain on thebattery 102 of the vehicle 100. In some cases, when the vehicle 100 isparked for an extended period of time, the key-off loads may cause asignificant reduction in the state of charge of the battery 102.

To address these key-off loads, the vehicle 100 may utilize the extendedpark mode application 124 to implement an extended park mode in whichkey-off load is minimized. The extended park mode application 124 may beone application included on the storage 122 of the body control module110. The extended park mode application 124 may include instructionsthat, when executed by the body control module 110, cause the bodycontrol module 110, in response to receiving an indication from a userinterface requesting to transition the vehicle 100 into an extended parkmode, to issue a command to the other modules 112 of the vehicle 100 tocause those modules 112 to transition to a reduced power mode (i.e., toperform operations to reduce their respective key-off loads on thevehicle 100). Accordingly, based on user direction the vehicle 100 maybe configured to reduce the load on the battery 102 during anticipatedextended vehicle stand times. The extended park mode application 124 mayfurther include instructions configured to cause the body control module110 to receive an indication from the user interface to transition thevehicle 100 out of the extended park mode, and provide a second messageto the modules 112 to cause the modules to return to normal operation.Further aspects of the operation of the extended park mode application124 are discussed in detail below.

When the vehicle is in the extended park mode, the modules 110, 112 maybe configured to perform operations to reduce their respective key-offloads on the vehicle 100. These operations may include, for example, (i)for modules 110, 112 that perform periodic polling of input, to slowdown or stop their polling, (ii) to disable periodic clock accuracyadjustments to allow the human-readable clock to drift, (iii) to turnoff tire pressure monitoring system (TPMS) monitoring, (iv) to turn offdoor sensors for passive entry features (e.g., excluding the driverdoor), (v) to limit embedded modem functionality and telecommunicationupdates, such as only to allow unlock, remote start and disable extendedpark mode, (vi) to disable approach detection features, (vii) to disablefuel operated heater systems, (viii) to disable extended play mode, (ix)to disable illuminated entry/exit lighting, (x) to limit or eliminatebattery saver duration control length of interior lighting, (xi) todisable powertrain wake on door ajar, (xii) to disable wake on oilminder, and (xiii) to disable global positioning system (GPS) updates.For hybrid or pure electric vehicles, these operations may also include,for example, (i) to discontinue cabin preconditioning, (ii) todiscontinue battery drive conditioning, and to (iii) disablescheduled-charge-not-occurring signals.

FIG. 2 illustrates an example system 200 including a cloud service 208in communication with a mobile device 204 and the vehicle 100implementing extended park mode. The communications network 202 mayinclude one or more interconnected communication networks configured toprovide communications services, such as Internet access, voice or dataover IP communications, short messaging service (SMS) and/or multimediamessaging service (MMS) communications, and location services, to atleast one connected device. As some examples, the communications network202 may include the Internet, a satellite link network, a wireless widearea network, and a cellular telephone network, as some non-limitingpossibilities.

The mobile devices 204 may include various computing devices configuredto communicate over the communications network 202 as well as to move inlocation with respect to the physical structure of the communicationsnetwork 202. Exemplary mobile devices 204 may include laptop computers,mobile telephones and smartphones, GPS devices, tablet computers, andthe vehicles 100 themselves for vehicles that include built-in modems.

The mobile devices 204 may be configured to provide a user interface 206from which the user may be able to configure the extended park modesetting of the vehicle 100. As one possibility, the mobile device 204may log into the cloud service 208, such as via a web browser of themobile device 204 connected to a web interface of the cloud service 208or by way of a client application of the mobile device 204 configured tocommunicate with the cloud service 208.

Additionally or alternately, the extended park mode application 124 ofthe vehicle 100 may be configured to provide a user interface 206 withinthe vehicle 100 from which the user may be able to configure theextended park mode setting, e.g., using the services of the userinterface module 112-G of the vehicle 100.

When the user makes a selection from the user interface 206 of thevehicle 100, the extended park mode application 124 may be configured toreceive the user input and adjust the extended park mode settingappropriately. When the user makes a selection from the user interface206 provided by the mobile devices 204, the mobile devices 204 may beconfigured to generate and send an extended park mode message 210 to thecloud service 208 over the communications network 202. The extended parkmode message 210 may include information indicating whether or not theuser wishes to place the vehicle in extended park mode. The extendedpark mode messages 210 may also include, for example, an identifier ofthe mobile device 204 making the request, an identifier of an account ofa user of the mobile device 204 making the request (e.g., phone number,e-mail address, etc.), and/or an identifier of the vehicle 100 whoseextended park mode setting is to be updated (e.g., vehicleidentification number (VIN) or some other unique vehicle 100identifier). As another example, the cloud service 208 may identify thevehicle 100 based on the information of the login session of the mobiledevice 204 with the cloud service 208 (e.g., web session information,client application session state, etc.). Further detail and exampleswith respect to the user interface 206 are discussed in detail belowwith respect to FIGS. 3-7.

The cloud service 208 may be configured to receive extended park modemessages 210 over the communications network 202 from the mobile device204, determine to which vehicle 100 the extended park mode messages 210should be directed, and forward the extended park mode messages 210 tothe appropriate vehicle 100.

When the vehicles 100 transition into and out of extended park mode, thevehicles 100 may be configured to provide park mode status updatemessages 212 to the cloud service 208. The park mode status updatemessages 212 may include information such as the current extended parkmode status of the vehicle 100, an identifier of an account of a userassociated with the vehicle 100 (e.g., phone number, e-mail address,etc.), and/or an identifier of the vehicle 100 whose extended park modesetting is updated (e.g., vehicle identification number (VIN) or someother unique vehicle 100 identifier). These park mode status updatemessages 212 may accordingly allow the cloud service 208 to track whichvehicles 100 are in extended park mode, and which vehicles are not.

Using the park mode status information regarding the vehicles 100, thecloud service 208 may be configured to filter out the sending of variousmessages by the cloud service 208. In an example, if the vehicle 100 isindicated as being in the extended park mode, then the cloud service 208may elect to defer the sending of software update requests to thevehicle 100.

FIG. 3 illustrates a diagram 300 of an example vehicle user interface206-A for selection of extended park mode. In an example, the userinterface 206-A may be presented to the user via display features of theuser interface module 112-G, e.g., upon selection of a vehicle settingsconfiguration option by the user. The user interface 206-A may include alist control 302 configured to display a listing of the vehicle settingsthat may be configured by the user as selectable list entries 304. Theuser interface 206-A may also include a title label 306 to indicate tothe user that the user interface 206-A is for selection of vehiclesettings, and a help information control 308 configured to provideinformation regarding the currently selected list entry 310.

As illustrated, the list control 302 of the connected applicationincludes an entry 304-A for a valet mode setting and an entry 304-B forthe extended park mode setting. It should be noted that the exactcommands, number of commands, and command order is merely an example.The list control 302 may operate as a menu, such that a user of the userinterface 206-A may be able to scroll through list entries of the listcontrol 302 (e.g., using up and down arrow buttons and a select buttonto invoke the selected list entry 310). In some cases, the list control302 may be displayed on a touch screen display, such that the user maybe able to touch the list control 302 to select and invoke a menu item.As another example, the user interface 206-A may support voice commandselection of the menu items. For example, to invoke the extended parkmode command, the user may press a push-to-talk button within thevehicle 100, and may speak the voice command “extended park mode.”

FIG. 4 illustrates a diagram 400 of an example vehicle user interface206-B for confirmation of selection of extended park mode. As with theuser interface 206-A, the user interface 206-B may be presented to theuser via display features of the user interface module 112-G. The userinterface 206-B may be displayed, for example, based upon a userselection of the extended park mode entry 304-B of the user interface206-A. The user interface 206-B may include a confirmation control 402displaying a prompt control 404 including information indicative of asettings change to be confirmed, and option controls 406 configured toreceive the user confirmation or rejection of the setting change.

As illustrated, the prompt control 404 includes information requestingthe user to confirm transitioning the vehicle into extended park mode.If the user selects the yes option control 406-A, then the vehicle 100may transition into extended park mode. However, if the user selects theno option control 406-B (or takes no action for a timeout period asanother possibility), then the vehicle 100 may not transition intoextended park mode.

FIG. 5 illustrates a diagram 500 of an example mobile user interface206-C for selection of extended park mode. In an example, the userinterface 206-C may be presented to the user via display features of themobile device 204. Content and user operation of the user interface206-C may be similar to that of the user interface 206-A discussed indetail above.

FIG. 6 illustrates a diagram 600 of an example mobile user interface206-D for confirmation of selection of extended park mode. In anexample, the user interface 206-D may be presented to the user viadisplay features of the mobile device 204. Content and user operation ofthe user interface 206-D may be similar to that of the user interface206-B discussed in detail above.

FIG. 7 illustrates a diagram 700 of an example vehicle user interface206-E for confirmation of removal of the vehicle 100 from extended parkmode. As with the user interfaces 206-A and 206-B, the user interface206-E may be presented to the user via display features of the userinterface module 112-G. In another example (not shown), the userinterface 206-E may be presented by the mobile device 204. The userinterface 206-E may include a confirmation control 402 displaying aprompt control 404 including information indicative of a settings changeto be confirmed, and option controls 406 configured to receive the userconfirmation or rejection of the setting change. The confirmationcontrol 402 of the user interface 206-E may be displayed, for example,by the vehicle 100 based on the extended park mode application 124receiving notification of a key-on of the vehicle 100 when the vehicle100 is in the extended park mode.

As illustrated, the prompt control 404 includes information requestingthe user to confirm transitioning the vehicle out of extended park mode.If the user selects the yes option control 406-A, then the vehicle 100may transition from extended park mode back to normal mode. However, ifthe user selects the no option control 406-B (or takes no action for atimeout period as another possibility), then the vehicle 100 may nottransition out of extended park mode.

FIG. 8 illustrates an example process 800 for requesting extended parkmode transitions via the cloud service 208. The process 800 may beperformed, for example, by the cloud service 208 in communication withthe mobile device 204 and the vehicle 100 implementing extended parkmode.

At operation 802, the cloud service 208 receives an extended park modemessage 210 from the mobile device 204. In an example, the cloud service208 may receive the extended park mode message 210 from the mobiledevice 204 responsive to user input to the user interfaces 206-C and206-D presented to the user via the mobile device 204. In anotherexample, the cloud service 208 may receive the extended park modemessage 210 from the mobile device 204 through a user interface 206 fromwhich the extended park mode may be disengaged. The extended park modemessage 210 may include information indicating whether or not the userwishes to place the vehicle in extended park mode. In some cases, theextended park mode message 210 may include additional identifyinginformation, such as an identifier of the mobile device 204 making therequest, an identifier of an account of a user of the mobile device 204making the request (e.g., phone number, e-mail address, etc.), and/or anidentifier of the vehicle 100 whose extended park mode setting is to beupdated (e.g., vehicle identification number (VIN) or some other uniquevehicle 100 identifier).

At operation 804, the cloud service 208 identifies the vehicle 100corresponding to the mobile device 204. As an example, the cloud service208 may identify the vehicle 100 based on identifying informationregarding the vehicle 100 included in the extended park mode message210. As another example, the cloud service 208 may identify the vehicle100 based on an existing login session of the mobile device 204 with thecloud service 208.

At operation 806, the cloud service 208 sends a request to the vehicle100 to request the vehicle 100 to transition the extended park modestatus of the vehicle 100. The request to the vehicle 100 mayaccordingly be configured to cause the vehicle 100 to transition to theextended park mode setting selected by the user via the user interfaceof the mobile device 204.

At operation 808, the cloud service 208 receives a park mode statusupdate message 212 from the vehicle 100. The park mode status updatemessages 212 may include information such as the current extended parkmode status of the vehicle 100. These park mode status update messages212 may accordingly allow the cloud service 208 to track which vehicles100 are in extended park mode, and which vehicles are not. Thisinformation may be maintained, for example, to allow the cloud service208 to only send messages to the vehicle 100 that are appropriate forvehicles 100 that are in extended park mode (e.g., only a limited set ofmessages such as door unlock, exit extended park mode, but not downloador install a software update). As an example, based on the current stateinformation, at operation 806 the cloud service 208 may only send therequests to the vehicle 100 to change the extended park mode settingwhen the cloud service 208 determines that the user has selected achange to the current extended park mode setting for the vehicle 100.After operation 808, the process 800 ends.

FIG. 9 illustrates an example process 900 for requesting extended parkmode transitions by the vehicle 100. The process 900 may be performed,for example, by the extended park mode application 124 of the bodycontrol module 110 of the vehicle 100.

At operation 902, the body control module 110 receives a request totransition the vehicle 100 into extended park mode. In an example, thebody control module 110 may receive the request responsive to receipt ofa message by the telematics control unit 112-D sent from the cloudservice 208 (e.g., as discussed above with respect to the process 800).In another example, the body control module 110 may receive the requestresponsive to input to the vehicle 100, e.g., via the user interface206-A and 206-B discussed above.

At operation 904, the body control module 110 sends a message to themodules 112 configured to cause the modules 112 to transition into theextended park mode. In an example, the body control module 110 maybroadcast a message across the vehicle bus 108 to the modules 112, wherethe message is configured to cause the modules 112 to be notified of thetransition into the extended park mode. Responsive to receipt of themessage, the modules 112 may be configured to perform operations toreduce their respective key-off loads on the vehicle 100.

At operation 906, the body control module 110 receives a request totransition the vehicle 100 out of extended park mode. In an example, thebody control module 110 may receive the request responsive to receipt ofa message by the telematics control unit 112-D sent from the cloudservice 208 (e.g., as discussed above with respect to the process 800).In another example, the body control module 110 may receive the requestresponsive to input to the vehicle 100, e.g., via the user interface206-F discussed above upon a key-on when the vehicle 100 is in theextended park mode.

At operation 908, the body control module 110 sends a message to themodules 112 configured to cause the modules 112 to transition out of theextended park mode. In an example, the body control module 110 maybroadcast a message across the vehicle bus 108 to the modules 112, wherethe message is configured to cause the modules 112 to be notified of thetransition out of the extended park mode back to the normal mode.Responsive to receipt of the message, the modules 112 may be configuredto perform operations to return to normal functioning. After operation908, the process 900 ends.

FIG. 10 illustrates an example process 1000 for performing extended parkmode transitions by the modules 112 of the vehicle 100. The process 1000may be performed, for example, by the modules 110, 112 of the vehicle100 to perform the operations to transition the vehicle 100 into and outof extended park mode.

At operation 1002, the module 112 receives a message to transition intoextended park mode. In an example, the module 112 may receive themessage responsive to operation 904 of the process 900, in which thebody control module 110 sends a message to the modules 112 configured tocause the modules 112 to transition into the extended park mode.

At operation 1004, the module 112 performs operations to reduce itsrespective key-off load on the vehicle 100. These operations mayinclude, for example, to slow or stop performance one or more module 112functions, examples of which are described in detail above. As themodule 112 may perform its own state adjustments, the module 112 may beaccordingly able to turn off functionality appropriate for the module112 while remaining in compliance with regulatory requirements.

These operations may also include the silencing of certain vehicle 100alerts that may be provided to the vehicle 100 owner during normaloperation. For example, for a plug-in hybrid, the vehicle 100 may turnoff the sending of scheduled-charge-not-occurring messages that may besent to a user when the vehicle 100 is scheduled to be charged but isnot. As another example, the plug-in hybrid may discontinue cabinpreconditioning that may be performed for a scheduled go-time for thevehicle 100, as the vehicle 100 being in extended park mode may overridepreviously scheduled trip departure times.

At operation 1006, the module 112 receives a message to transition outof the extended park mode. In an example, the module 112 may receive themessage responsive to operation 908 of the process 900, in which thebody control module 110 sends a message to the modules 112 configured tocause the modules 112 to transition from the extended park mode into thenormal mode.

At operation 1008, the module 112 performs operations to return tonormal functioning. These operations may include, for example, to resumenormal speed or otherwise resume performance one or more module 112functions, examples of which are described in detail above. Afteroperation 1008, the process 1000 ends.
